In the title compound, C(22)H(21)BrN(4)O(2), the imidazole and pyrazole rings are almost orthogonal to each other, but the ester unit is effectively coplanar with the adjacent aryl rings. The molecules are linked into a chain of edge-fused centrosymmetric rings by a combination of N-H···O and C-H···π(arene) hydrogen bonds.
